BRACKET.

Specification of Letters Patent.

Patented March 10, 190 8.

Application filed May 14, 1906. Serial No. 316,875.

To all whom it may concern:

Be it known that I, ISAAC POVALL, a subject of the King of England, andresident of Des Moines, Polk county, Iowa, have invented a new anduseful Bracket, of Which the following is a specification; 1

The object of this invention is to provide improved means for detachablyconnecting two members, such as a table and leg, a post and brace, andsimilar devices.

My invention consists in the construction, arrangement and combinationof elements 'hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which Figure 1 is anelevation, partly in section, illustrating my improved device asemployed to connect a table and leg. Fig. 2 is an elevation, partly insection, showing my improved device as employed to connect a studdingand joist. Fig. 3 is an elevation illustrating my improved device asemployed to connect a post and brace. Fig. 41 is a face viewillustrating the complete bracket, and Fig. 5 is a cross-section of thesame.

In the construction of the device as shown the numeral 10 designates asocket member, preferably made of metal by molding, and formed withmarginal flanges 11, 12, the inner faces of said flanges opposite eachother and in converging planes. Lugs 13, 14 are formed on and extendtoward each other from the central portions of the flanges 11, 12 andthe inner faces of said lugs are spaced apart from the outer face of themember 10. The member 10 also is formed with a plurality of screw-holes15 adapted to admit screws as shown by dotted lines in Fig. 2 to securethe said member to a support such as a table 16, studding 17 or post 18.A keymember 19 is provided and preferably is formed of metalby molding.The key-member 19 has its side margins in converging planes and isformed with ribs 20,21 projecting laterally from said side margins andhaving their outermost margins in converging planes. The extreme widthof the keymember and ribs conforms to the width of the member 10 betweenthe marginal flanges 11, 12 and the thickness of the ribs conforms tothe space between the inner faces of the lugs: 13, 14 and the outer faceof the socket member. The key-member 19 is formed with a centralbolt-hole 22 openinglat the inner face of said member to a square cavity23 adapted to contain the head of a bolt 24, said bolt and a nut 25adapted to secure said key-member to a table-leg 26, a joist 27, or abrace 28 The socket-member 10 may be mounted on one device in anydesired position, dependent on the direction in which strain is to beapplied thereto, and the key-member 19 may be applied to a mating devicein corresponding position to enter and by strain or weight engage thesocket-member. As the strain increases as by increase of weight orjarring in use, the key-member engages more firmly in the socket member,and yet may be readily and conveniently removed therefrom when it isdesired to disconnect the devices carrying the bracket-members.

I claim as my invention 1. A bracket, comprising a socket member,marginal'flanges on said socket member and having their inner facesformed in converging planes, lugs on said flanges and spaced apart fromthe socket member, the inner faces of said lugs being parallel with theopposite face of the socket member, and a key member having ribs on itsside margins, said ribs adapted to enter freely between the lugs andsocket member and the body of the key member extending outward beyondthe outer faces of the lugs, the converging margins of the ribs adaptedto engage the converging inner faces of the flanges on the socketmember, and the lugs adapted to engage the key member.

2. A bracket, comprising a socket-member formed with converging groovesopposite each other, said grooves square in crosssection, saidsocket-member also formed with screw holes, and a key-member formed withconverging marginal flanges, said flanges also square in cross-sectionand adapted for longitudinal seating in said grooves, the outer face ofthe key-member being outside the plane of the outer face of thesocketmember, the side margins of said key-member being in convergingplanes and adapted to enter between and engage the opposite sides of thesocket-member outside the con- Signed by me at Des Moines, Iowa, thisverging grooves, said key member also sixth day of May, 1905.
